Probably not. Early boot graphics is controlled by the BIOS. So if the BIOS has chosen not to light up a monitor by then, we can't use it till the OS and full graphics driver stack loads later. Usually the BIOS will only display on one monitor, whichever it deems to be primary.
GRUB probably has no notion of "monitors". At that stage there is only a graphics framebuffer (EFI/VBE/VGA) provided by the BIOS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2110949 Title: No output to USB-C monitor after logging in with the laptop closed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2110949/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
